GraphType can take values from 0 to 8, as shown above.
However, parameters 5 through 8 are only available when
purchased as a separate option. The assignment of
graphType depends on which domain is specified. (Note
that this list of values for graphType may be retrieved using
the FETC:GNAM? query, below.)
Decimate can be set to 1 to use decimation, or 0 to return
all points.
Description: Retrieves the size of the data arrays; i.e. the number of data
samples to expect from the FETC:MEAS? queries.
All parameters must be specified.
